Nice jugs you got there. I remember using these on vacation trips, picnics, etc. as a kid. My grandmother had a couple of them in two sizes, one for water and one for Kool-Aid or iced tea. No bottled water, no soda - and no ice. Outings and events for school, church, etc. always included a giant orange cooler-jug and waxed-paper cups.
My sister and I were musing the other day at how we never got to "eat out" at restaurants when traveling, there was always a picnic meal, ate at a rest stop or park along the way. Almost nothing was thrown away but a few paper napkins, the rest was packed up, washed and used again on the journey home.
